The iambic trimeter derives its name from its essential shape, which is three metrical units (hence trimeter) which are each basically iambic in form. The iambic metron has the following shape (where the x is an anceps, the - is a longum, and the u is a brevis):
Hence, reversing the current running though a wire will have the affect of reversing the direction of the magnetic force at a point some distance away from the wire. The affect that this has on the overall magnetic field depends on the shape of the wire.
If a coil is rotated as shown, in a magnetic field pointing to the left, in what direction is the induced current? A) clockwiseB) counterclockwiseC) no induced current Conceptual Quiz As the coil is rotated into the B field, the magnetic flux through it increases. According to Lenzâs law, the induced Bfield has to oppose this increase, thus the new B field points to the right.
